What is pick up of a relay?
The "pick up" of a relay is a setting at which the relay will begin to operate. Such as an overcurrent relay - if the pickup is set to 5A, when 5A is flowing through the relay, the relay will operate.
What is the difference between a relay and an auxiliary relay from constructionapplication poin of view?
I think aux relay is part of relay

What is dmt and idmt relay?
DMT relay stands for definitive mean time, and IDMT stands for inverse definitive mean time. In IDMT relay, there is a minimum time delay with magnitude.
How is a IDMT relay used to give protection against a phase to earth fault a phase to phase fault on a feeder?
As with any IDMT relay the higher the fault current the quicker the trip time.
What is IDMT What is the principle?
IDMT stands for Inverse Definite Minimum Time. It is a protection relay characteristic commonly used in power systems to provide protection against overcurrent conditions. The principle of IDMT is that the tripping time of the relay is inversely proportional to the magnitude of the current, such that higher overcurrents result in faster tripping times to quickly isolate the fault and prevent damage to the system.
What is the function of IDMT relay?
i working 66 kv and 220 kv substation. over substatin transformer and 66 kv sf6 bracker use i intersted for working of idmt realys with breacker tripping coil.

What is lt idmt curve?

What is the difference between idmt and dmt?
idmt means inverse definite minimum time. so in this type of relay as the value of operand that is current increase time taken by the relay to operate decrease. higher the current lower is the time taken by the relay to operate. AND dmt definite minimum time (DMT) relay take its minimum time to operate regardless of the value of the current. The definite mean time lag in disc type EM relays is inverse to current as the disc is faster at higher current and hence the less time.Definite mean time lag is possible in static relays by setting the time lag.
DIFFERENCE BETWEEN IDMT AND DMT?
The CT associated with the DMT, IDMT, inverse, very inverse and extremely inverse possess different characteristics. In particular, Inverse and IDMT CT’s have different operating points on their magnetic characteristics. i.e. Both have different saturation levels.
What is IDMT stand for?
Inverse Definite Minimum Time
What is psm tsm for idmt relay?
PSM stands for Plug setting multiplier and can be found on the front of the relay module in the form of a scale . PSM = Actual or fault current in the relay / ( CT Secondary current X Amp setting in the relay) From the above value of PSM find the time in seconds from the front of relay panel scale i.e., PSM Vrs Time in seconds Miltiply the time in seconds with the TSM to find the tripping time for the relay for the specific value of fault current TSM = Time setting multiplier Relay Operating time = TSM x time in seconds <- as observed from the scale .
What afsc is 4n051c?
Aerospase Medical Service Journeyman, Independent Duty. Otherwise called IDMT.
What is idmt over current relay with different plug setting multiplier?
Any nonlinear load on a system generates harmonics. Exampes are the magnetic core of a transformer or equipment which uses rectifiers to produce direct current. The triplen harmonics are unpopular because they add on a three-phase system, so they produce current in the neutral, which a three-phase system in balance does not.
